TERY and SEMION Sardinia, citizens of United S ates, and residents of Chica o. in the count; of (look and State of lliinnis, lave invented certain new and useful improvements in Devices for Locating and liaising;

Sunken Boats, of which the following is a. lull, dear, and. exact srmcd'ication.

I it M leis hi devices lot which t lorm ti lunction nnlependently of devices locating and raising boats in for raising a heat and which consists respee 1 tiveiy of a lleat and grappling device.

The prime object of this invention is-io utilize the device for locating a sunken boat as a means l'or directing; and guiding crap-- ating as to render the engagement of the grappling; device with a sunken boat absolutely certain, whether lixl' boat be in an upright or tilted position, and by such means that the accidental disengagement of the grappling device from thea ai is wzu'tieiill impossible.

A: further chic-c of onr '1 ion utilize the locating derive tor tzrreriuug' 5mpplingdevices to' an engagement w is n a sunken boatat the best and pre leiernunate point or cints thereon, best -adapted to:- raising a cat to the surface.

r-ruoiherobject is to hare tilt grappling; devices so constructed and arranged that they may be convenientlyseparated from the boat after being riser and se 'ured and which is desirable in view of the enormous weight such grappling devices must neces-- r to raise large absolute certainty. Fig. 2, a side elevation partly in section of grappling device embodying our invention but out oi engagement with each other. Fig. 3, a side elevation oi the ion relates to improvements in device. for locating: the boat per glue the boat, and to have such device so eon trueted and etn'iperl same showing the position of the grappl device on thecone when about to be lowered to engagement with the cone fo raisinar a sunken 'essel. Fig. i, a detail \iew ilhi.-;-- tratinu -the adaptability (if th heating derices for directing the grappling: device to rug; men! w th a vessel. the de k f which, as shown in SWiiOIl, is tilted and l'ig. 5, a detail showing enlarged perforations for the rods comm-ting t1 gripping jaws and limitint: the spread of saidjawsf Similar numerals of reference indicate the saine parts in the several figures of the drawings ti indicates a vessel to the deck, T, or suit able portions or timbers thereof, are secured a l)2l t"{)li\it N, by means of bolts, 9, and mounted upon this base-plate and seetired thereto by rivet lti, or or her suitable means are opposing: brackets or lugs, ll -li,lbetween which is h nged a, yoke, l), by means yoke by means at a hoe k of peculiar constru-znion, that is to say, which consists of a stein, if) by which the iitit'iii is direct l r hing to the yoke anda cone shaped body, ua, pr, vi ed at its base with an undercut, 17, forming adjacent the periphery of the cone a continuous hook, 18%.

(Foam 16, is provided with a longitiulina-l perforation, it), extending; from the recess, i7, through the upper free and pointed end of the cone and paralleling the incline sides of the cone hook as shown in Fig.

Passing upwardly through perforation, 19, and knotted or otherwise enlarged atits lower end to prevent its detaehnu-nt by an upward puli, is a. cable or rope, '20, which is of such a, length that a float, 2i, secured on the free i end thereof will rise to the surface of any i depth of water in Wliltll the boat may have I sunk, and therebyindicate on the surface the location of such sunken boat, and for this purpose there may be one or more such devices secured to the deckof a boat or at any point below the deck but passing upwardly therethrough.

The hOOkJSLI'UULl I'P/ ust described is in practice secured to the boat at the best possible point for grappling the same in raising the boat to the surface, and for which purpose our invention includes a separate and distinct device adapted to cooperate therewith and which consists of two separate movable jaws, 22--22, perforated at their uppcr ends, as indicated at 23, and strung, so to of a pivot. l-J, etween the arms of .twhicl',

pivot, 14, 1s lunged. a.

-may be guided and limited in these movemerits by means of oneor more, and prefer- I ably two bolts, 25, passing through larger perforations, 26, (see Fig. in the body of the jaws, the clamping portions of which jaws are formed by right-angular bends, 27

and 28, therein, each of which is provided in its edge with a semi-circular cutout portion,

- 29, forming when the jaws are closed a circular opening for the reception ol the point of "the cone, whereby the jaws are thereby gradiially spread apart'until below the base of the cone when they will swing in toward each other beneath the baseand in engagement therewith.-

of whatever length may be necessary to lower clamping aws l'IOill the s irlnae to the base of the cone on the sunken boat and the heavy, the rods, 25, limiting senses to pass over the point of the cone and be locked to the base thereof, as before described.

As the, grappling devices must necessarily very strong and therefore correspondingly and directing the movement of the jaws to engage them with the cone are so constructed as to be removable, tl at is to say, are provided with nuts as indicated in Fig. 2 so that the jaws may be eonwnicntly disengaged from the 1 cone alter the Vessel is raised. Ring, 24,.has attached thereto a cable, Lil

"jaws together with the cone constitute a:

. suspendingthe jaws.

grappling device therefor as will now be ex' plained.

gThe locating device which essentially con- 1 sists of a rope secured to the cone in U rn secured, as before described, to the vessel, and

secured at its opposite end to a lloat which together with the rope when not in \ni! rests upon the deck ol a vessel or imiy lc in a re ceptacle of some kind on or below the deck 1 provided with a cover which will ally open and release the lloat :is soon as the automaticboat sinks below the surface of the water, the I rope being of such a length that toe lloat will 3 rest on the surlace oi; the water at whatever depth the vessel may be.

With the boat thus located by l he lloat, the float with the rope is taken hold of and'raised out of the water until practically in a ycrti cal line when the rope, 20. preferably passed through the ring, 24', as indicated in Fig. 3, and the jaws by their cable are then lowered to the cone hook, the rope 2U, oi which thereby serves to guide the jaws thereto with such accuracy that if the rope, 20, is taut, as it should be to hold the cone in a vertical POSltlOllythB jaws will pass over the point of and down the cone until they swing inwardly engaged with and are firmly locked to the cone-and in a'positio'n enabling the raising-oi'the boat by pulling on the cable In this connection it should-be observed that the hinging of the "cone so that. as before described, provides in practice there may be its many grappling cone hooks located as many dii'l'erent points on the vessel at may be deemed advisa le lor the raising of the vessel and also there may be as many ol' the grappling jaw devices carried upon the wrecking or other \"Qbstl nr-ay lo necessary to use in the raising ol a s. nken vessel.

The shank ol the grappling hook might be connected with the deck ol the vessel by a lull and socket joint. but in practice the bolts of i3 and l l are prclerred [or the reason that great strength of joint is necessary and. which is be {or provided for by the bolts than is practical by ball and socket joint connection.

llziving described our invention, what we claim and desire to scrurc by Letters latcnt 1 grappling hook lilttllls for securely hingiug said hook to the deck ol a boat, a lloai, a rope connecting said float and hook and gripping aws and a ring from which said jaws are looselys:ispended, a cablesecurml to said ring and suspending said jaws, and bolls passing through said jaws and limiting their movement away from each other, substantially as described.

in witness whcrcol', we have herminto set our hands and allixed our seals, this 7th day of March l 1906.
